We look at the division of 85603919 by 987 
Our goal is to divide 85603919 by 987.

Step 1:
987 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 987

Advancing to step 2:
85 divided by 987 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 987

Step 3:
987 goes into 856 0 times with a remainder of 856.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 856 after subtracting 0 from 856.
Take the next digit (0) from the dividend and append it to 856, then repeat: 8560 / 987

On to step 4:
When dividing 8560 by 987, we get 8 with a remainder of 664.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7896 from 8560 leaves us with 664.
Append the next digit (3) from the dividend to 664 and continue with: 6643 / 987

Going ahead to step 5:
When dividing 6643 by 987, we get 6 with a remainder of 721.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 5922 from 6643 leaves us with 721.
Bring next digit (9) of the dividend behind the 721 and repeat the process: 7219 / 987

Moving on to step 6:
987 goes into 7219 7 times with a remainder of 310.
Record the quotient 7 as the next digit in the result. 
Result so far: 867.0
If we take 6909 away from 7219, we end up with 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 987

Step 7:
The number 987 fits into 3101 3 times, leaving a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 8673.0
Subtracting 2961 from 3101 leaves us with 140.
Take the next digit (9) from the dividend and append it to 140, then repeat: 1409 / 987

Step 8:
The number 987 fits into 1409 1 times, leaving a remainder of 422.
The number 1 becomes the next digit in our result. 
Result so far: 86731.0
If we take 987 away from 1409, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 9:
4220 divided by 987 is 4 with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 86731.4
Deduct 3948 from 4220 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
The number 987 fits into 2720 2 times, leaving a remainder of 746.
The number 2 becomes the next digit in our result. 
Result so far: 86731.42
Subtracting 1974 from 2720 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Advancing to step 11:
987 can be fit into 7460 7 times, resulting in a remainder of 551.
Put 7 as the next digit of the answer. 
Result so far: 86731.427
Deduct 6909 from 7460 and we're left with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Let's proceed to step 12:
5510 divided by 987 is 5 with a remainder of 575.
The next digit of our result is 5. 
Result so far: 86731.4275
If we subtract 4935 from 5510, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 13:
987 can be fit into 5750 5 times, resulting in a remainder of 815.
Use 5 as the next digit of our solution. 
Result so far: 86731.42755
Deduct 4935 from 5750 and we're left with 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

In conclusion, the division gives 86731.42755 with a balance of 0.000815.
